ABSTRACT

A system and method for electronically transferring funds in a gaming environment is disclosed. The system includes a memory device operable to store a game value and memory device interface operable to retrieve data from, and transfer data to, said memory device. The memory device interface may be integrated into an electronic gaming machine or proximate a live table game. Monetary value may be added to the memory device by casino personnel or a kiosk. A player may then use the memory device to download credits to a gaming machine or in exchange for game chips at a live table game. Machine credits may also be added to the memory device for later use at a another machine. Credits may also be stored on a casino system for access based on identification of the player facilitated by the memory device.

FIELD OF THE INVENTION

The embodiments of the present invention relate to an electronic transfer of funds system implemented in a gaming environment. With such a system and method, casino customers are able to purchase credits from a casino cashier or kiosk and then proceed to play the purchased credits at electronic gaming machines (e.g., slot machines) or live table games within the casino or other commonly owned casinos.

BACKGROUND

In today's casino market the most popular means of transferring funds between electronic gaming machines is via the use of paper tickets. Such tickets have turned gaming into a generally cashless endeavor. In one exemplary situation, a player approaches an electronic gaming machine (or device), inserts cash and proceeds to play the game. When the player is ready to leave the machine, the player simply presses the ‘cash out’ button and the machine prints a ticket for the remaining credit on the game. The ticket may then be cashed in at a cashier or kiosk, or inserted into another machine, read and redeemed as machine credits.

The current ticket system suffers from several problems including 1) the requirement for a significant background accounting system to authenticate the transactions and maintain security; and 2) the system is expensive to use. Casinos in Nevada have disclosed that the cost of such a system runs as much as $3.00 per ticket. In addition, the ticket printers (one per machine) cost about $600.00 each and frequently break down.

Thus, there is a need for a cost-effective system that eliminates tickets and ticket printers in the gaming environment.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles in accordance with the embodiments of the present invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive feature illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.

The operation of electronic gaming machines (e.g., slot machines) is controlled by microprocessors which communicate with internal memory devices and the external features of the machines. The microprocessors also incorporate, or communicate with, a random number generator which ensures the randomness of the machines' outcomes. Since the technology for operating and controlling electronic gaming machines is well-known to those skilled in the art, the subtle details are not described herein.

Like electronic gaming machines, player tracking systems are well-known in the art. Such systems track the play of registered players. Players identify themselves to the casino using player or slot cards which can be inserted into, and read by, electronic gaming machines. Upon being read, a player database is accessed such that new information from the current play session can be used to update the player's database. Player cards may also be used at live table games where casino personnel swipe the card to access the player's database. Gaming information may then be entered manually or via the use of RFID systems now finding there way into casinos. Since the technology for operating and controlling player tracking systems is well-known to those skilled in the art, the subtle details are not described herein.

Reference is now made to the figures wherein like parts are referred to by like numerals throughout. FIG. 1 shows a block diagram of a gaming system generally denoted by reference numeral 100. The system 100 includes a plurality of electronic gaming machines 110-1 through 110-N and a central computer system (e.g., a server) 120. The server 120 may be running player tracking system software 121 and accounting system software 122 among other conventional casino software. Each gaming machine 110-1 through 110-N includes a memory device interface 130 integrated on the machine 110-1 through 110-N for engagement with a memory device as explained in more detail below.

FIG. 2 shows a memory device 150 in the form of a silicon microchip 151 housed in a button or similar container. Dallas Semiconductor (a subsidiary of Maxim Integrated Products located in Sunnyvale, Calif.), located in Dallas, Tex., manufacturers an iButton® of the type that can be used to facilitate the embodiments of the present invention. The memory device 150 may be fabricated of stainless steel or other durable material. In this instance, the contained microchip 151 stores at least a game value associated with the memory device 150. However, as set forth below, the memory device 150 may also include personal information (e.g., name, ID number, etc.) associated with a purchaser or holder of the memory device 150. The memory devices 150 may also include unique and unalterable addresses laser etched onto the microchip. The addresses may be used as an identifier for each memory device 150. FIGS. 3 a and 3 b show the memory device 150 contained within a carrying case 155. An opening 156 in the carrying case 155 allows the memory device 150 to be attached to a lanyard or similar item so that it may be conveniently carried throughout a casino with minimal risk of loss.

FIG. 4 shows a memory device interface 160 integrated on an electronic gaming machine 110. The memory device interface 160 may be integrated anywhere on the gaming machine 110. The memory device interface 160 is adapted to read output from the memory device 150 and relay input to the memory device 150. The memory device interface 160 may be DS2460 and DS1963S data carriers also manufactured by Dallas Semiconductor. Associated software is also utilized to analyze data and authenticate memory devices 150. The memory device interface 160 includes a protruding pin 165 having a flat end surface 170. As shown in FIG. 6, the memory device interface 160 is sized to receive and engage the memory device 150 so that the flat end surface 170 of the memory device interface 160 contacts a data contact surface of the memory device 150. Through this contact, the memory device interface 160 is able to read output from the memory device 150 and relay input to the memory device 150 in a preprogrammed manner as described below. Power is supplied to the memory device 150 via the memory device interface 160. In one embodiment, a magnet 157 on said memory device 150 and/or memory interface device 160 maintains engagement between the memory device 150 and/or memory interface device 160. FIG. 5 shows a memory interface device 160 separated from the electronic gaming machine 110. A cable 165 connects the memory interface device 160 to one or more backend programs, like the player tracking software 121, accounting software 122 or related software. Alternatively, the cable 165 connects to a local processor at the machine level. Dedicated and/or proprietary software may also be used to manage the electronic funds transfer (EFT) system embodiments of the present invention. In one embodiment, a wireless mesh network and backend database may facilitate the EFT system.

FIG. 7 shows a flow chart 200 detailing one method embodiment of the present invention. At 205, a player acquires and loads a memory device 150 with value loaded thereon from casino personnel. A player may load the memory device 150 with any dollar amount (e.g., $25 to $1000) permitted by the casino. At 210, the player next locates an electronic gaming device 110 he or she desires to play. At 215, the player attaches the memory device 150 to a memory device interface 160 integrated in the electronic gaming device 110. At 220, the authenticity of the memory device 150 is verified by backend software in communication with the memory device interface 160 and/or machine processor and/or central server 120. At 225, upon verification of the authenticity of the memory device 150, the dollar amount stored on the memory device 150 is transferred to the electronic gaming machine 110 and displayed in the form of game credits on a machine credit meter. Optionally, in addition, a player database is accessed. Alternatively, the player database is only accessed in response to a player of slot card or similar device being read by the gaming machine 110. Authenticating and/or verifying the memory device 150 may comprise a correspondence of the memory device's unique identifier number mentioned above. For example, the authentication may involve a 64-bit Authentication Secret known to the memory device 150. The 64-bit Authentication Secret may be derived from the unique identifier and a master secret. Authentication may also involve a 24-bit Challenge value sent to the memory device 150 prior to the authentication of the data in the memory device 150. The 24-bit Challenge value is randomly generated at the start of each transaction and changes for each transaction. Other authentication and verification schemes and/or systems may be used as well. A game session then transpires at 230. In response to the player electing to cash out (e.g., pressing the machine's cash out button or cash out icon on a touch screen), it is determined, at 235, whether the memory device 150 remains engaged to the memory interface device 160. If so, at 240, existing machine credits are transferred or downloaded to the memory device 150. If not, at 245 a visual and/or audio message instructing the player to re-engage or re-attach the memory device 150 is sent to the gaming machine 110. At 240, in response to the reattachment of the memory device 150, the existing machine credits are transferred to the memory device 150. Optionally, at 250, simultaneously with the transfer or download of the existing credits, information regarding the gaming session is downloaded into the player's database accessed at 225. A player may then move to another gaming machine 110 and attach the memory device 150 to begin play or may proceed to a cashier or kiosk to collect any monies stored on the memory device 150.

While the description herein focuses on electronic gaming machines 110, the EFT system according to the embodiments of the present invention may also be utilized at live table games. In such an embodiment, each gaming table has a memory device interface 160 linked to a dealer monitor proximate the table. The monitor may be a dummy or smart device. As a dummy device, the processing power may be supplied by a central server or similar device. In one embodiment, there maybe 7 or 8 memory device interfaces 160 corresponding to each player location at the table. Dealer monitors are commonly used with player card readers to track play at live table games based on pit boss input or RFID chip input. With the embodiments of the present invention, as a player approaches a live table game he or she takes a seat and hands the memory device 160 to the dealer who attaches it to the single memory device interface 160 (or the one memory device interface 160 corresponding to the player's seat location) to obtain a game value associated therewith. Once the game value is determined, the dealer provides the player with a desired value of game chips. If the value of the game chips is less than the full value stored on the memory device 150, the dealer uses a monitor interface to deduct only a portion of the value thereby leaving the remaining value balance on the memory device 160. If only one memory device interface 160 is used, the memory device 150 is then returned to the player until the game session ends. If memory device interfaces 160 are available for each player location, the dealer maintains the memory device 150 attached to the corresponding memory device interface 160. Once the player is ready to leave, the player may simply leave with any remaining chips and the memory device 150 or “cash in” whereby the dealer adds the player's chip value to the player's memory device 150 in exchange for the player's chips.

In another embodiment, player credits are stored on the system 100. For example, player credits may be stored on the server 120 in a player account. The player account may be the player tracking account or another designated account. In this embodiment, the memory device 150 is used as an identifier at a machine 110 or gaming table. In such an embodiment, the player first deposits cash or similar value with the casino. The casino then causes the player account, maintained by the server 120, to be credited the amount of the deposit. Then, when the player desires to play a machine 110 or a live game of chance, the player uses the memory device as an identification tool for access to the stored credits. In a machine example, once the identification of the player is verified and authenticated, the stored credits or a portion of the stored credits are transferred to the machine for play. Once the gaming session ends, any machine credits are either stored on the system 100 for later use or may be cashed out by the player. In a live game of chance example, once the identification of the player is verified and authenticated by the dealer, the player may request a desired amount of gaming chips based on the stored credit amount. The dealer then causes the stored credit amount to be adjusted based on the gaming chips provided. After the game session ends, the player may either turn in the chips for credit to the system 100 or may retain the chips for use at another table or cash them in.

In any of the embodiments disclosed herein, players may also be issued passwords or other unique codes which must be provided prior to funds being transferred from the memory devices 150 or stored player accounts. In one example, players use a touchpad or touch screen on the gaming machines 110 to enter the code to verify their identity. Thus, once the memory device 150 and player identification are verified, the funds can be moved. A dealer may enter the code at the live table games. In another embodiment, players must insert their player card along with the memory device 150 so that the two can be authenticated and verified. Other means of protecting funds stored on the memory devices 150 or player accounts may also be implemented as desired by casinos and required by regulatory bodies.
